Gear up for great views of comets and a ton of other celestial sights with the Orion 20x80 Astronomical Binocular & Paragon XHD Tripod Bundle! This value-packed bundle includes our eXtra Heavy Duty Paragon-Plus XHD field tripod and a pair of our powerful 20x80 Astronomical Binoculars.

With great features such as high-transmission BAK 4 porro prisms, fully multi-coated optics, and gigantic 80mm (3.14") aperture objective lenses, our Orion 20x80 Astronomical Binoculars will astound you and your friends with its amazing viewing capability. Their giant 80mm objective lenses gobble up light from objects in the night sky, yielding bright views across a 3.2° field-of-view with exceptional contrast and sharpness. These big and powerful binoculars gather almost 500-times the amount of light your eyes can; and they collect over 30% more light than 70mm binocular models for brighter views of comets, star clusters, bright planets, the Moon and other cosmic curiosities. During the day, these 20x80 binoculars will amaze you with 20-power views of wildlife, scenery, and other daytime targets. Their 17mm eye relief makes viewing comfortable, even if you wear corrective eyeglasses while you observe. An integrated heavy-duty tripod adapter lets you easily attach the binocular to the included Paragon-Plus XHD Tripod for comfortable and stable tripod-mounted viewing sessions during the day or at night.

The included Orion Paragon-Plus XHD Tripod features large, adjustable aluminum-tube legs with robust lock lever clamps for convenient setup and takedown. Each tripod leg features graduated reference etchings so you can quickly and easily extend each leg to the same preferred length - a great time saver when trying to setup in a hurry. This Paragon-Plus XHD Tripod is 67" tall when fully extended, which will put the included 20x80 Astronomical Binoculars conveniently at eye level for most observers. The tubular aluminum tripod legs measure 1-1/4-inch maximum diameter; and each leg is laterally braced with dual 3/4" aluminum tubes for enhanced stability. The tripod legs are tri-braced to the center elevator housing for extra stability. The central elevator post is 1-1/8" diameter, and features 11-3/4" of vertical travel. Height of the tripod when fully extended is 67", and it collapses down to a nicely portable 34".

The tripod's two-way fluid-type pan head is equipped with tension adjustment knobs on both axes for wonderfully smooth, controlled altazimuth (up/down and left/right) motion with the 20x80 binoculars attached. The pan head can be raised or lowered on its aluminum rack-and-pinion elevator post with a hinged hand crank. Panning the included binoculars around the sky or horizon is easy with the tripod's 11"-long adjustable handle. A quick-release 1/4"-20 dovetail shoe makes attaching and detaching the included 20x80 binoculars from the pan head easy and convenient. Other nice features on the tripod include convertible cushion/spike feet and built-in bubble level.

This complete stargazing and daytime viewing solution will help you enjoy views of comets and other interesting sights while its affordable price will help you keep your wallet full!

Warning

Please note this product was not designed or intended by the manufacturer for use by a child 12 years of age or younger.

Magnification

Also commonly referred to as "power", magnification is a measure of how much closer an object appears when viewed through the instrument. For example, a 10x binocular will make an object appear 10-times closer than it would normally appear. An object positioned 100 yards away would appear as if it was just 10 yards away in a binocular with 10x magnification. The human eye is considered 1x magnification.

Optical diameter

For telescopes, the optical diameter (also known as aperture) is the size of a telescope's main light-collecting lens or primary mirror, measured in millimeters or inches. Telescopes with larger optical diameters collect more light, which leads to an increase in brightness and image resolution compared to smaller instruments.

For binoculars, the optical diameter (also known as objective lens diameter) is the size of each of the front-facing objective lenses of a binocular measured in millimeters. Binoculars with larger objective lenses collect more light, which increases image resolution and brightness. Binoculars with larger objective lenses are recommended for low light situations, and binoculars with at least 50mm or larger objective lenses are recommended for pleasing astronomical observations at night.

Field of view - angular

The field of view expressed as part of a 360-degree circle. Holding your pinky finger out at arms length is approximately 1-deg wide. To convert this to the linear measurement of "feet at a thousand yards", multiply by 52.5. For example, at 1000 yards distance, a 7-deg binocular will see a width of 367.5 feet (7 x 52.5)

Apparent field of view

The edge-to-edge angular diameter of the image displayed in a binocular as seen by the eyes of the observer. It is an inherent specification for a given binocular design. The "angular diameter" of an object is defined as the angle an object makes (subtends) as seen by an observer.

Eye relief

The distance, measured in millimeters, between the observer's eye and the eyepiece lens in which the entire field of view remains visible. Eye relief varies with the optical design but generally increases with decreasing magnification. Long eye relief is advantageous for observers who wear glasses, as they don't have to put their eye directly on the eyepiece to see the entire field of view, nor do they have to remove their eyewear.

Exit pupil

The diameter of the circle of light exiting the binocular. Exit pupil is calculated by dividing the objective lens diameter by the binocular magnification. For example, a 10x50 binoculars has an exit pupil of 5mm (50/10=5). Knowing the exit pupil of a binocular can help determine the optimal binocular fro your needs. If a binocular exit pupil is larger than the dilation of the user's pupil, resolution is reduced since the maximum amount of light is not entering the eye. Typically under true dark adaptation a healthy human eye will dilate to approximately 7mm. This number can decrease with age and health factors.

Near focus

The minimal distance at which a binocular and/or spotting scopes can attain focus. Near focus is an important quality for bird watchers and wildlife devotees who want to get as close as possible to their quarry.

Coatings

Binocular lenses and prisms are often coated with anti-reflective material to minimize light loss as light travels through the multiple optical surfaces of a typical binocular. Coatings help maximize the amount of light transmitted through each glass surface of a binocular, so as much light as possible reaches the observer's eyes to provide a bright and sharp image.

Good lenses are at least "fully coated," with a single layer of magnesium fluoride coating applied to each air-to-glass lens surface. Multiple layers of coatings are even more effective; the term "multi-coated" means one or more air-to-glass lens surface has multiple coatings. "Fully multi-coated" optics are even better, meaning all lens surfaces have multiple layers of anti-reflective coatings applied for maximum light transmission and optimal image quality.

Prism

Porro Prisms:

A binocular prism system that contains two right-angle prisms in each barrel offset from one another, requiring that the objective lenses be spaced further apart than the eyepieces. Optically, porro prisms often perform better than their roof prism counterparts.

Roof Prisms:

A compact binocular prism system that allows the objective lenses to line up directly with the eyepieces and hence yields a more portable binocular. Roof prism binoculars lose slightly more light to reflections than porro prism binoculars. High-quality roof prism binoculars compensate for this with special optical coatings.
